Our notes

The C800 Plus puts 768 Wh and a 1,200 W inverter in a 24 lb box with built-in camping lights. That output runs a drip coffee maker and a CPAP for about 22 hours. A microwave at 1,500 W is out of reach.

There's no published surge rating, only a 1,600 W SurgePad figure. A typical full-size fridge needs about 1,200 W for a moment at startup, exactly the inverter's continuous rating, so a fridge (about 11 hours of runtime) is borderline, and a sump pump can't be confirmed from the specs.

Wall charging is fast (full in 58 minutes at 1,100 W), solar tops out at 300 W, and it can't take an extra battery. Anker marked it "Last Chance" in September 2026. If you want the same class with a published surge and more capacity, the C1000 has 1,056 Wh and a 2,400 W surge rating at 28.4 lb.

Simulated runtimes (not measured)

Nobody tested this unit for this page. These figures come from a computer simulation of the C800 Plus, and they are estimates. The plain runtime table below divides energy by average draw at 85% efficiency. The simulation also charges the battery for the power the inverter burns just by being switched on, which is why small loads come out shorter. Where we have measured a unit, the measurement is shown separately and labeled as measured.

Simulated runtimes for the Anker SOLIX C800 Plus
Device	Spec-sheet math	Simulated, typical	Likely range	Simulated at 0 °C
Wi-Fi router + modem	44 hours	23 hours	19 hours to 28 hours	20 hours
CPAP (no humidifier)	22 hours	15 hours	14 hours to 17 hours	13 hours
Starlink Standard	7.3 hours	6.5 hours	6.2 hours to 6.9 hours	5.5 hours
Refrigerator (full-size, ENERGY STAR)	11 hours	9.3 hours	8.7 hours to 10 hours	7.9 hours

Nonstop runtime from full to battery cutoff. Likely range = middle 80% of 200 simulated runs with the uncertain inputs varied. The inverter idle draw is assumed, not published: we assumed about 15 W for this model, varied from 9 to 23 W. If the real figure is lower, real runtimes land closer to the spec-sheet column.

How this was simulated

The battery is stepped down every 2 minutes until it reaches cutoff, for 200 runs per device. Results are seeded, so the page shows the same numbers on every build.
Battery draw = load + inverter idle draw + 4–8% of the load + a loss that rises with load squared (4% at full output).
Usable capacity = 92–98% of rated Wh, for protection cutoff and aging.
At 0 °C, 80–90% of that capacity is assumed available.
Fridges cycle on and off every 30–50 minutes at the share of the time set by their average draw. The inverter idle draw continues while the compressor is off.
Devices that exceed this model's output or surge rating are left out. Loads are US 120 V devices.

Surge? = this model has no published surge rating, so starting motors and compressors may or may not work. Fridges, freezers, pumps and AC units cycle on and off, so we use their average draw. Want a mix of devices on a schedule? Use the runtime calculator.

Questions

How long will the Anker SOLIX C800 Plus run a refrigerator?

About 11 hours for a typical ENERGY STAR full-size fridge averaging 58 W, assuming 85% inverter efficiency. Older or larger fridges use more. Try your own numbers.

Can the Anker SOLIX C800 Plus run a microwave?

Not a full-size one. A typical 1,000 W microwave pulls about 1,500 W from the outlet, more than its 1,200 W continuous output. Its SurgePad mode is meant for simple heating devices, and microwaves may not work properly with it.

How many amp-hours is the Anker SOLIX C800 Plus?

The Anker SOLIX C800 Plus works out to about 64 Ah at 12 V, or 60 Ah at 12.8 V, the nominal voltage of a 12 V LiFePO4 battery. Both are our conversion of Anker SOLIX's 768 Wh rating: amp-hours = watt-hours ÷ volts. The battery inside may run at a different voltage, so an amp-hour figure in a manual or on a product listing can look very different for the same energy. For scale, a 12 V 100 Ah LiFePO4 battery holds 1,280 Wh, so this model holds about 60% as much as one. How we convert amp-hours.

How long does the Anker SOLIX C800 Plus take to charge?

Anker SOLIX's published charging claim: “100% in 58 min (HyperFlash AC)”. Max AC charging power is 1,100 W. With solar, it accepts up to 300 W. With 300 W of panels that's roughly 3.4 hours of good sun from empty.

Is the Anker SOLIX C800 Plus expandable?

No. Its capacity is fixed at 768 Wh.

Does the Anker SOLIX C800 Plus work as a UPS?

Anker SOLIX lists a 20 ms switchover time, so it can keep devices like routers and computers running when the power drops. Check that your specific device tolerates the switch before relying on it for anything critical.
